本文将对现代光谱发展的重要新技术——中阶梯光栅和电视检测技术的原理、性能和应用作简单的综述。一、中阶梯光栅光谱仪至今,发射光谱分析的重要问题之一,就是光谱仪器的分辨本领和色散率限制了某些问题的解决。例如,测定钢铁中的碳和硼,发射光谱分析经常使用的 This article briefly reviews the principles, performance and applications of the key new technologies in the development of modern spectroscopy - the mid-raster and television detection technology. First, the ladder grating spectrometer Up to now, one of the important issues of emission spectroscopy analysis is the resolution of spectroscopic instruments and dispersion rate limits the solution of some problems. For example, the determination of carbon and boron in steel, often used in emission spectroscopy
